Kristy Manzanares was found dead Tuesday night as the cruise ship Emerald Princess traveled between Ketchikan and Juneau.

Her husband, Kenneth Manzanares, was charged with murder after he was discovered with blood on his hands and clothes, and with blood spread throughout the cabin on the Princess Cruises ship, according to a criminal complaint by FBI Special Agent Michael L. Watson.

"Kristy was a dedicated and loving mother who juggled her business schedule to make her children the top priority," the statement from Summit Sotheby's International Realty in St. George, Utah, said.

Kristy Manzanares, 39, had a severe head wound, but authorities have declined to release other details in the case, including how many people were traveling with the couple on the 3,400-passenger Emerald Princess that left Sunday from Seattle.

A man and other people went into the room before medical workers and security officers had arrived and saw the woman on the floor covered in blood, according to court documents.

The man asked Manzanares what happened, and the suspect said, "'She would not stop laughing at me,'" according to the FBI complaint.

Manzanares then grabbed his wife's body and tried to drag her to the balcony, but the man stopped him, Watson wrote. The name of the man was not included in the complaint.

A ship security officer handcuffed Manzanares, who was held in a nearby cabin, authorities said.

While the FBI searched him, Manzanares said, "'My life is over,'" the complaint states.

Passengers aboard the ship at the time of the incident said they initially believed the commotion was a hoax as any had been attending a "murder mystery" themed dinner when an announcement was read over an intercom saying a "domestic altercation" had occurred.

"Whoever was talking was pretty scared because their voice was shaking," one passenger, Ruby Plata, told CBS News.

Another passenger, Chris Ceman, had been just across from the room the alleged murder took place.

"One of the little girls from that room came running out, calling for help, that her parents had been in a fight. She sounded pretty desperate, but the crew came up as quickly as they could," Ceman told CBS. "It became apparent last night that something serious had happened, but we didn't know how serious."
